About 30 analogues of BAPTA-AM, a potential antithrombotic agent, have been synthesized and tested for their effect on the production of prostacyclin. None of them was found to be a better enhancer of the production of prostacyclin by aortic endothel

2,3-Diphenylquinoxaline-N-oxide 1 with thionyl chloride gives only 5-chloro- and 6-chloro-quinoxaline and very little deoxygenation. Phenazine-N5-oxide 2, in the same conditions, gives mainly 2-chlorophenazine and minor amounts of 1-chlorophenazine,

Cu(l) and Ag(l) complexes of 1,4,5,8-tetra-azaphenanthrene (TAP) and of two of its methylated derivatives (3,6-dimethyl- and 2,3,6,7-tetramethyl-) have been made and characterized. Their HNMR spectra are discussed. The structure of the complex Ag(TAP

The secretion from ventral glands of Craesus alniastri, Craesus septentrionalis, and Craesus latipes (Hymenoptera, Tenthredinidae, Nematinae) was analysed by GC–MS. The terpenoid dolichodial was the major compound in the three species. A few other

The alkaloids of two coccinellid beetles, Calvia14-guttata and C.10-guttata have been studied. The major alkaloid of these two species is the new piperidinic cis-lactone 1a, for which the name calvine has been coined. The corresponding trans-lactone
